Cable-free independent long-term working landslide hazard landslide hazard monitoring early warning method and system

Abstract

The invention discloses a cable-free independent long-term working landslide hazard monitoring early warning method and system. The cable-free independent long-term working landslide hazard landslide hazard monitoring early warning method reasonably arranges rock soil wireless sensing sensors on a surface layer and a deep layer of a landslide slop, wherein, preferably, the rock soil deformation wireless sensing sensor is self-powered with low power consumption, performs wireless communication with a monitoring base station, does not need power supply and a communication cable, and does not need extra protection after installation. Furthermore, the rock soil deformation wireless sensing sensor is small in volume, simple in installation and low in cost, can independently work for at least 5 years, and thoroughly solves a difficulty that a cable of a monitoring system is easy to damage. When the landslide slope is deformed, the cable-free independent long-term working landslide hazard monitoring early warning method realizes real-time and effective monitoring on landslide slope integral deformation and local deformation like collapse, sliding, and the like according to deformation magnitude and corresponding positions which are obtained by the rock soil deformation wireless sensing sensor; when the deformation magnitude exceeds a preset value, a device installed near the landslide slope alarms, so that people on the periphery is timely and quickly evacuated to a safe area and the risks of the landslide hazard are reduced and eliminated to the greatest extent.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to a landslide disaster monitoring and early warning method and a monitoring and early warning system that can work independently for a long time without cables. Background technique [0002] Landslide disaster refers to the disaster caused by the rock mass or soil mass sliding down the slope under the action of gravity, which is a phenomenon of slope instability. Landslides widely occur in mountains, plateaus and hilly areas, and are the main natural disasters hindering the social and economic development of mountainous areas. [0003] Due to the widespread distribution of landslides, the suddenness of landslide disasters, and the limitations of existing monitoring techniques, there is no good monitoring and early warning method for landslide disasters at home and abroad. There are many existing landslide monitoring instruments, and they are gradually developing from ...

AI Technical Summary

Problems solved by technology

There are many existing landslide monitoring instruments, and they are gradually developing from manual monitoring to remote real-time monitoring. At present, many field rock and soil monitoring instruments have the problem of field installation and protection. The destruction of body deformation will cause great interference to the implementation of long-term unattended and remote real-time automatic monitoring, and it is also prone to wrong early warning behaviors, resulting in unnecessary countermeasures. These problems seriously restrict the existing remote monitoring early warning technology Widely popularized and applied in landslide disasters
